Hata Sadanosuke (1868 - ?) was a Japanese businessman who built a historic structure called the S. Hata Building in Hilo, Hawaii, in 1912. It now contains specialty shops, professional offices, a restaurant, and the Mokupāpapa Discovery Center, a visitors center for the Leeward Islands. Sadanosuke's younger brother Hata Yoichi (1884 - ?) was another notable Japanese businessman who founded a major wholesale food distribution company in Hawai'i.
